Internal Cylindrical Grinding of Longer Parts

Ideal for the internal grinding of longer workpieces for machine tools, drive elements, aerospace and toolmaking jobs, the Studer S141 universal ID cylindrical grinding machine from United Grinding combines cutting edge technologies with optimal ergonomics and ease of use. 

The S141 grinding spindle turret accommodates up to four grinding spindles (including a maximum of two external grinding spindles), a universal measuring probe and internal grinding quills in lengths up to 10.433 in (265 mm) for both internal and external machining of workpieces in the same clamping, minimized noncut times and boosts in part accuracy. With a direct-drive integrated swivel axis and high-resolution measuring system, the turret rotates/positions quickly and precisely for repeatability of less than one angular second.

United Grinding North America, Inc. (Miamisburg, OH) offers the Studer S141 universal ID cylindrical grinding machine that offers the ability to internally grind longer workpieces common to the machine tool, drive element, aerospace and toolmaking industries. The S141 combines both cutting edge and proven technologies with optimal ergonomics and ease of use, while delivering dependability, quality and precision.

The S141 features two big sliding doors for optimum accessibility and is available in three different design sizes to machine workpieces with maximum lengths of 11.81 in (300 mm), 27.56 in (700 mm) and 51.18 in (1,300 mm) and inside diameters up to 9.84 in (250 mm). These grinding capacities make the S141 ideal for processing chuck components, spindle shafts, spindle housings, rotor shafts and other such parts.

The grinding spindle turret accommodates up to four grinding spindles (including a maximum of two external grinding spindles), a universal measuring probe and internal grinding quills in lengths up to 10.433 in (265 mm). This allows both internal and external machining of workpieces in the same clamping, minimizes noncut times and boosts part accuracy. With a direct-drive integrated swivel axis and high-resolution measuring system, the turret rotates/positions quickly and precisely for a repeatability of less than one angular second.

In addition to a workhead that can be direct or belt driven, the S141 workpiece table automatically swivels from -10 deg to +20 deg via the machine control for axis parallel grinding of tapers. Up to two pivoting dressing units for fixed or rotating dressing tools mount on the machine and ensure the grinding wheels stay sharp throughout the machining operations to provide maximum performance and process stability.

The S141 features a machine bed made of patented Granitan® S103 mineral casting
that dampens vibration and provides excellent thermal stability for superior surface
quality and workpiece accuracy. The machine also incorporates the StuderGuide®
system for its X and Z axes. They are coated with Granitan S200 wear-restistant
guideway surfacing material for the highest precision and load bearing capacity as
well as strong damping across the machine’s entire speed range.

With its ergonomic and user-friendly design, the S141 changes over in the shortest
times possible and is easily reprogramed. The machine’s 31i – B series Fanuc
Control with integrated PC and a 15 in touch screen facilitates intuitive operation. Two
different operating systems – StuderWIN and StuderSIM – are available and suitable
for a wide variety of internal grinding applications, dressing and process-supporting
measurement.
